WIRE-NAIL MACHiNE.

SPECIFICATION forming part of Letters Patent N o. 397,067, dated January 29, 1889.

Application tiled March 12, 1887. Serial No.` 230,597. (No model.)

To all whom it 11mg/ concern.'

Be it known that I, Fosnns'rnn BRYANT, of New Haven, county of New Haven, and State of Connecticut, have invented an Improvement in Nail-Making Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings represent-ing like parts.

This invention relates to wire-uail-making machines, and is an improvement upon the machine shown and described in my application, Serial No. 188,088, filed January IS, 1880, it having for .its object to improve and simplify the construction of the same.

In the machine shown in the application referred to, the head of the nailis formed by a punch o1header,7 and after being acted upon by the cutters the nail is precipitated into a receptacle by an independent finger or knocker-ofl'. In accordance with my present invention I dispense with the independent linger or knocker-o'tf, and make the header perform the double otlice of header and knocker-otf, my improved header pei'- mitting a longer nail to be cut with less throw et' the crank operating the said header. In this particular my invention consists in the combination, with the mechanisms for feeding, cutting, and gripping or holding the wire, of a block arranged in a reciprocating carriage and acted upon by a cani to rock it at intervals, the said block receiving and supporting' the header.

Another feature of my invention consists in pivoting or hinging to the floor or to a support thereon the stand supporting the reel from which the wire is taken, so that the said stand maybe turned on its pivot or hinge toward the machine in Aease the wire becomes entangled,the said stand as it approaches the machine acting' to turn a lever to operate upon the feeddog carriage to remove the dog out ot engagement with. the wire, and thereby prevent the wire from being ted.

My invention further consists in making the jaws which hold the cutters and the mechanism operating them ot such construction, as will be hereinaftei.' described, as to relieve the same of upward pressure, the said upward pressure tending to lift the jaws bodily, and in such case if any lost motion ensued at the pivots of the jaws the wire would be bent upward, so that when the header struck the wire it would form. `the head of the nail on one side of the longitudinal center of the wire.

Other features ol:l my invention will be pointed out in the claims at the end of this specification.

Figure l is a plan view of a nail-making machine construct-ed in accordance with my invention and of the reel to support the wire connected thereto; Fig. 2, a longitudinal section of the machine on line a, the reel and its supportingstand being in elevation, the fly-wheel being omitted. Fig. 3 is a detail showing more clearly the connection between the cutter-carriers and the mechanism operating them, Fig. 4, a detail to be referred to; and Fig'. 5 is a modilication.

The main shaft A, having bearings in the top frame, A,of the machine,supported upon standards A2, is provided with a crank, a, to which is secured the connecting-rod d', provided with the usual strap, o?, the said shaft having the usual belt-pulley, (IVX, and fly-wheel AW. The connecting-rod d has secured to it by a pin, a3, a rocker, (shown as a block,) a, to which is vfastened the punch or header cr", that forms the head of the nail, the said pitman bein g extended through the said rocker and havingbearings in a cross-head or carriage, a, the said cross-head being reciprocated in suitable guideways at each revolution of the main shaft, the said rocker being turned or rocked on the pitman a3, for a purpose to be hereinafter described, at each reciprocation of the cross-head.

The rocker o", as shown, is provided at its' under side with an arm, o7, (see Fig. 2,) preferably having at its end a roller, as, which rides upon the upper surface ot' a cam-block, l), secured, as shown, by screws b b2 to the frame A', the said arm being herein shown pressed down upon the said cam-block by a spring, 2. The roller as normally rests upon the highest part of the cam-block, as shown in Fig. 2, when the header is forming the head of the nail. As the rocker d4 and cross-head a are moved backward through the connect ing-rod, the roller as travels down the inclined surface, as 3, ot the cam-block, thus turning' the rocker on its pivot and lifting the header up out of line with the wire.

'.lhe wire is fed Vffrn'ward from a reel, l1", by a feed meehanism,herein shown as a Carriage, L, provided with a longitudinal bore or hole, b, throug'h which the wire is extended after passing through straghtening-rolls 21X, eommon lo nail-making machines, the said wire being' passed between dies bf bs, the lower die, Z13, being' seeured by the bolt b9 to the frame A,and the upper die, hlby the bolt 'bw to the 1o pivot-ed arm b, the said arm being aeted upon to eause the dies to firmly grip the wire while the header is acting' to form the head of a nail by the arm e, pivoted at e to a lever, e2, pivoted at to the frame A', and having its 1 5 long' arm :Jg acted upon by a eatin, 5, (shown in dotted lines, Fig'. 1,) on the main shaft, the said eam acting' upon the lever (f2 as the head er eonnnenees its forward stroke, the parts just mentioned operating' Substantially as in the zo apjilieation referred to.

The earriag'e b is provided with uprig'hts d, to which is pivoted a lever, d', provided with a dog', (Z2, to engage the wire and feed it forward as the earriag'e is moved forward in 2 5 the guideway (13.

The earriag'e is moved forward and baek ward b v a feed meehanism Consisting', as shown, of an arm, (Z1, having' one end extended into al socket in the under side of the said 3o carriage, the other end of the said arm being' secured to a rock-shaft, d, havingI bearings in the frame A', the said rock-shaft having' an upright arm, d, Connected to one end of a pitman, (ZT, having' its other end pivotalljv se- ;5 cured to a bleek, als, fitted into the dovetail slot in the disk el, secured to or forming' part of the main shaft.

The stand e, suppm'ling' the reel f, is pi voted io lugs e?, secured to the Hoor, and is 1.o Connected b v the rod e3 to the short arm of a lever, el, pivoted to the frame A, and having' its long' arm (5 extended upward and provided, as shown, with a stud, (ZX, the said stud standing' in the path of movement of the lever d.

i5 If the wire should beeome entangled, the stand e wouldv be drawn toward the machine, it turning' upon its pivot.

As the stand e is drawn toward the machine, the rod e3 aets upon the lever e" to 5o move its long' arm L from its full into its dotted line position, Fig'. 2, and when in the latter position the stud dx will be struck by the lever d on the next forward movement of the fee l-earriage Il", thus turning' the lever d on its pivot and lifting the dog' d2 out of en ment with the wire, Consequently perm the feed mechanism 1o reeiproeate the earriag'e b5 without feeding the wire. The feed mechanism is so timed with relation to the 3o movement oli' the rocker d'1 and erossshead a thatthe wire fed forward as the said roeker and Cross-head are withdrawn or are on their l iaek ward movement.

A su flieient length of wire having' heen fed 3 5 forwartfl to form a nail of desired lengtlnwhieh length ean be varied by ehanging' the posi tion of the bleek d8 in the dovetail slot in the disk d, the said wire is aeted upon byentting' knives or dies ff.

The eutt-in( dies f j" are secured to like cutter-earl'iers,j"2 fi", one at each side of the machine, and hot-h being' alike l shall, speeifieallj' describe but one, as The eutterearrier f2 at its lower end is made as a voke secured, asherein shown, to a journal orspindie, f, having its bearings in the frame A.

rlhe journal f" at one end, as herein shown, is reduced in diameter to form a stud, f, upon whieh is mounted a sleeve, f, threadelfl on its outer surfaee 1o eng'ag'e threads in the opening' in the frame A. (See Fig'.

The stud f is threaded at its end to be engaged by a washer, f", and nut f8, the said washer and nut acting' to keep the sleeve f abut ed against the end of the journal f4, as elearlj7 shown in Fig'. 4. The (futter-earrerj2 is adjusted forward and backward, as described, by means ol' the sleevejl.

The cutter-carrierf2, as shown in Fig. 5l, is recessed at one sidenear its top to reeeive a ball, g, on one end of a link, g', having' at its opposite end a ball, g2, to enter a 11a-essor socket in the side of an arm or upright, y, of a sleeve, gx, mounted on a shaft, g, the said shaft having' bearii'lgs in lugs .(/f g on the frame A. (See Fig'. l.)

The sleeve g* near the rear of the maehine is provided with a depending arm, f/T, shaped, as shown .in Fig'. I3, to extend toward the eenter of the machine, the inner end ol' the said depending' arm being' preferably provided with a threaded opening' to receive a threaded pintle, g8, having' its ends ballshapetfl to enter sockets in metal slippers y gw; but instead of the thri-iiaded pintle l may employ a ball, lo, attaehed to the arm gl, and forming' Vwith the metal slippers a universal joint, as shown in 'Fig'.

The metal slippers g" g1 are supported in a housing', m, forming' part of an eeeentriestrap, m', embracing' the eeeentrie m2 on the main shaft A, as shown in Fig'. 2, the vertical movement of the eeeentriestrap 'm' and hous ing' ml imparting' a roeking' movement to the sleeve gx and arm g and permitting' the said slippers to slide in the said housiiig'. The rocking' motion of the arm g3 is transferred to the eutter-earrier f2 through the link g to roek the said eu'rter-carrieron its join-naif'l to produee a movement of the Cutting-dies toward and from the, wire held bythe dies 117118. The eutttmearrier f3 is operatively eonneeted in a similar Amanner to that described for the eutter-earrierf2. As shown in VFig'. 3, the link g', eonneetii'lg the eutten Vfarrier f2 with the arm g3, is longer than the link eonneeting the eut- 1er-carrier f with the arm g3 on the opposite side of the maehine, as the housing` m is on one side of the hmg'itudinal eenter of the maehine.

l'nstead of the l)all-ai1d-soeket eonlleetion shown for joining' the earrier f and arms au, the rod g may be pivoted thereto.

It will be notieed that the pressure exerted lOO IIO

to move the cutter-carriers is a side pressure, and is received by the carriers above their pivots.

In the operation ot' my improved machine the wire fed `forward by the feed mechanism is gripped and iirmly held by the dies c7 bs, while the header upsets the end of the wire to form the head ol' a nail. The rocker a* and cross-head a are then withdrawn by the connecting-rod a. As the cross-head al5 is withdrawn, the roller as travels down the incline 3 ot' the cam-block '1), the spring 2 keeping' t-he said roller in engagement therewith. As the roller travels down the inclined surface of the cam-block, the rocker c is turned or rocked on the pitman a3 to lift the header out of line with the wire. The cutting-dies are then brought together to sever the nail from the wire, the said cutting-dies serving to point the nail. The rocker CL4 begins to be moved forward with the header in its elevated position at the same moment the cutting-dies are severing the nail from the wire, the said header and rocker passing over the nail until the roller as arrives at the foot of the incline El ol' the cam-block D.

On the further forward movement of the cross-head a the roller as begins to ascend the incline 3, thereby turning the rocker to bring the header into its normal or horizontal position, the cutting-dies at such time having severed the nail from the wire, the said'header serving to knock the said nail into a suitable receptacle (not shown) located below the machine in case the nail be not entirely severed 'from the wire. After knocking the nail from the wire, the header is moved forward in a straight line io 'form the head of the nextnail.

By means of my improved rocking headerI am enabled to cut a longer nail with a less throw ofthe crank than if the said header were reciprocated in line with the wire, and also to dispense with an independent finger or knocker-olf.

I do not desire tolimit myself to a camblock located below the rocker, as the said block may be above, and, if desired, it may act directly upon the said rocker.

I claiml. In a wire-nail-making machine, a wirefeeding mechanism, a cuttingl mechanism to sever the wire, and a gripping mechanism to hold the wire while being acted upon, combined with a rocker arranged in a carriage and provided with a normally-depressed depending arm, a header carriedby said rock-er and mechanism to reciprocate the said carriage, and a cam co-opcrating with the said depending arm to rock the said rocker, substantially as described.
